GB/T 4340.1-2009 Specify the Vickers Hardness test method for metal materials. Vickers Hardness is a key indicator to measure the performance of metals. The standard specifies the applicable range of metal materials and elaborates the test principle, that is, the use of specific indenters to form indentation on the metal surface to determine Hardness. Specify the technical parameters, accuracy requirements and calibration method of test equipment, such as Vickers hardness tester. Specify the sample preparation, covering surface roughness, size, etc. Strictly stipulate the test operation, including the size of the loading force, loading time, measurement indentation diagonal length, etc. Give the Hardness value calculation and result representation method to ensure the accuracy and reliability of the test, and help the metal mass detection and application.
